Neutral network-based automatic coal drawing system and method for fully mechanized coal mining face

The invention discloses a neutral network-based automatic coal drawing system for a fully mechanized coal mining face. The system comprises a system host (1), an electrohydraulic control system (2) and a plurality of hydraulic support pressure monitoring devices (3), wherein the system host (1) obtains external information through manual input or automatic transmission of the hydraulic support pressure monitoring devices (3), analyzes and processes the external information, processes and calculates the external information through a neutral network model to obtain a command signal, and transmits the command signal to the electrohydraulic control system (2); after the electrohydraulic control system (2) receives the command signal sent by the system host (1) or sent manually, the electrohydraulic control system (2) controls the opening and the closing of a coal drawing hole (44) of a fully mechanized coal mining face hydraulic support (4); the hydraulic support pressure monitoring devices (3) are used for monitoring the top coal pressure borne by the hydraulic support in real time and transmit monitoring data to the system host (1) in real time. The system can effectively solve the problem that automatic coal drawing is poor in adaptability to top coal thickness change and top coal and roof condition difference of the hydraulic support.
